Say Hello to OpenTalk - the future of secure video conferencing

View of the secure videoconferencing solution Opentalk with five participants

We are pleased to announce the start of the introductory phase of OpenTalk - our new video conferencing solution at This is an exciting event for colleagues at our sister company, which was founded in 2021. OpenTalk offers a user-friendly, secure, and digitally sovereign video conferencing experience. Thanks to its open-source code base and modern IT architecture, the software is GDPR-compliant and supports special requirements and sessions with many users.

“Good communication starts with independence. And that is exactly what the development of OpenTalk represents: a secure alternative to other video conferencing solutions that offers true data autonomy.“ says Markus Michels, CEO of OpenTalk.

As of today, all subscribers to a PREMIUM or STANDARD price plan can go ahead and test OpenTalk. The feature is accessible through the menu bar after login, which now has a new video conferencing icon. Alternatively, users can log in directly at using their regular login credentials.

Initially, OpenTalk will be available as an additional option alongside our existing video conferencing solution Jitsi. After the introductory phase has ended, Jitsi will be replaced completely by OpenTalk, as the latter offers a much better user experience, improved security, and better features to meet the requirements of provider operations. Like our other services, operates the new video conferencing solution within our own data centre in Germany.

An idea becomes OpenTalk

How did OpenTalk actually come about? Over the last two years, the work lives of many people have changed dramatically. Our team members, too, suddenly found themselves working remotely and experimenting with different video conferencing solutions. As it happened, Heinlein Support had been commissioned to set up a video conferencing platform for the administration of the city of Berlin around the same time. Any of the existing solutions, most of which hosted in the US, were not acceptable for data protection reasons. We wanted a video conferencing solution that respects the digital sovereignty of its users and that can be operated independently. As for existing open-source solutions, we found that these suffered from image quality and performance issues, which made them difficult to scale for deployment at a professional level in a provider environment like that of

We soon realised that we weren't getting anywhere with those existing solutions. Instead, we realised that we can create what we need, and more: a solution that is more modern, more comfortable to use, more secure and, of course, open-source! The founding of OpenTalk as a product development company was the logical consequence, and our team quickly developed ideas for a whole range of features that would make a video conference experience more productive and user-friendly. And then they got to work and started developing that solution.

The launch of OpenTalk marks an important milestone for digital sovereignity and security for video conferences.
